I have four of the 8×16 panels from the Kickstarter. I am looking to mount them to a wall. I was thinking of something along the lines of the top one (“Profile 5 20 x 10”) at http://www.valuframe.co.uk/Series-5-Aluminium-Profiles.html – but I think they’re too big (that’s the smallest they do, with 5mm holes in the nuts that fit in the slot, but my micrometer says the mounting holes in the panels are just under 4mm).

I posted a 3D printable case on Thingiverse (http://www.thingiverse.com/thing:243804)
that would work as a wall mount. It was built for 16×16 but can easily be adapted to
meet your 4x8x16 application.
